Abstract (en)
[origin: WO2018091696A1] The invention relates to a display mechanism comprising a moving part (110) carrying, with conjoint rotary movement, a first wheel and a cam (112, 212) in a spiral arrangement, the mechanism taking on a first, active state in which the first wheel is rotated by a driving moving part, and a second, zero reset state in which it is no longer driven in order to allow it to return to a predefined position, associated with a predefined position of the display body, the display mechanism also comprising a touch probe (116, 216) that can cooperate with the edge of the cam (112, 212), the touch probe (116, 216) and the edge of the cam (112, 212) being arranged and dimensioned in such a way that the touch probe (116, 216) exerts on the cam (112, 212), in the second state, a restoring force having a non-radial component for bringing the first wheel into the predefined position thereof.
